Description

{APPARATUS AND METHOD FOR TIRE PRESSURE MONITORING}

The present invention relates to a tire pressure monitoring device and method.

There are two ways to measure tire pressure: direct and indirect. In the indirect method, four wheel speed sensors are placed on each wheel, and the wheel speed is analyzed to determine the corresponding diameter and frequency, and tire pressure is measured based on the analysis results.

The tire pressure monitoring system (TPMS) learns tire pressure and performs tire pressure warning control using the learned tire pressure as a reference value.

At this time, the tire pressure monitoring system learns the tire pressure when the user operates the tire pressure setting button and stores the learned tire pressure as a reference value.

However, if the user arbitrarily operates the tire pressure setting button when the tire pressure is low, the tire pressure monitoring system will learn the low tire pressure and set the standard value for the low tire pressure warning too low. In this case, the tire pressure system will not sound an alarm even when the tire pressure is low, which can lead to a dangerous situation.

The purpose of the present invention is to provide a tire pressure monitoring device and method that improves stability and reliability by preventing incorrect tire pressure from being learned in the event of an incorrect operation of the tire pressure setting button by determining whether to allow a tire pressure setting button based on a result of determining whether a tire is inflated.

In addition, another object of the present invention is to provide a tire pressure monitoring device and method that can determine whether a tire is inflated at low cost by using a camera or an ultrasonic sensor when determining whether a tire is inflated.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, according to one embodiment of the present invention, a tire pressure monitoring device comprises a sensor unit that detects an object within a predetermined area set around a plurality of tires, and a control unit that determines whether an object is detected within the predetermined area for a predetermined period of time or longer to set an allowable or disallowable state of a tire pressure setting button, and determines whether to learn tire pressure based on the set state of the air pressure setting button when the air pressure setting button is operated.

The above sensor unit is characterized by including a plurality of sensors each detecting an object located within first to fourth areas set around each tire in a tire low pressure warning state.

The above plurality of sensors are characterized by including a camera sensor that captures an image of the surroundings of the vehicle including the first to fourth areas.

The above plurality of sensors are characterized by including ultrasonic sensors that each detect an object located within the first to fourth areas.

The above control unit is characterized in that, when it is confirmed that an object is detected within the first to fourth areas for a certain period of time in the tire low pressure warning state, the tire air pressure setting button is set to an allowable state.

The above control unit is characterized in that, when the air pressure setting button is operated and the tire air pressure setting button is in an allowable state, the control unit learns and stores the tire air pressure.

The above control unit is characterized by outputting a notification message that guides the completion of storage of the tire air pressure.

The above control unit is characterized in that, if it is determined that an object is not detected for a certain period of time within at least one of the first to fourth areas in the tire low pressure warning state, the tire air pressure setting button is set to a non-allowed state.

The above control unit is characterized in that, when the air pressure setting button is operated and the tire air pressure setting button is in a non-permitted state, learning of the tire air pressure is blocked.

The above control unit is characterized by outputting a warning message guiding the confirmation of the status of the tire air pressure.

In addition, the device according to the present invention is characterized by further including a judgment unit that determines whether an object is detected for a predetermined period of time or longer within each of the first to fourth areas based on object detection information from the plurality of sensors.

The above control unit is characterized by outputting a tire low pressure warning when the tire pressure is detected to be below a standard value.

In addition, a tire pressure monitoring method according to one embodiment of the present invention for achieving the above purpose is characterized by including a step of detecting an object located within a predetermined area set around a plurality of tires, a step of checking whether an object is detected within the predetermined area for a predetermined period of time or longer to set an allowable or disallowable state of a tire pressure setting button, and a step of determining whether to learn tire pressure based on the set state of the air pressure setting button when the air pressure setting button is operated.

According to the present invention, by determining whether to allow the tire pressure setting button based on the result of determining whether or not the tire is inflated, it is possible to prevent incorrect tire pressure from being learned in the event of an incorrect operation of the tire pressure setting button, thereby improving stability and reliability.

In addition, according to the present invention, there is an effect of being able to determine whether a tire is inflated at low cost by using a camera or an ultrasonic sensor when determining whether a tire is inflated.

FIG. 1 is a drawing illustrating the configuration of a tire pressure monitoring device according to one embodiment of the present invention.

The tire air pressure monitoring device (100) according to the present invention can be implemented inside a vehicle. At this time, the tire air pressure monitoring device (100) can be formed integrally with the internal control units of the vehicle, or can be implemented as a separate device and connected to the control units of the vehicle by a separate connecting means. As an example, the tire air pressure monitoring device (100) can be implemented in the form of a tire air pressure monitoring system (TPMS) inside the vehicle.

Referring to FIG. 1, the tire pressure monitoring device (100) may include a control unit (110), a sensor unit (120), an output unit (130), a communication unit (140), a storage unit (150), and a judgment unit (160). Here, the control unit (110) and the judgment unit (160) of the device (100) according to the present embodiment may be implemented as at least one processor.

The control unit (110) can process signals transmitted between each component of the tire pressure monitoring device (100).

The vehicle is equipped with tires on the front left (FL), front right (FR), rear left (RL), and rear right (RR), respectively. The sensor unit (120) detects an object, i.e., a person, located in an area around the four tires equipped on the vehicle. Here, the object detection area around the front left (FL) tire can be defined as a first area, the object detection area around the front right (FR) tire can be defined as a second area, the object detection area around the rear left (RL) tire can be defined as a third area, and the object detection area around the rear right (RR) tire can be defined as a fourth area.

Here, the sensor unit (120) may include multiple camera sensors that capture images of the surroundings of the vehicle. The multiple camera sensors may capture images of the front, rear, left, and right directions of the vehicle. The images acquired by the multiple camera sensors may be images that capture a 360-degree area around the vehicle.

An example of an image acquired by multiple camera sensors is shown in Fig. 2a.

Referring to FIG. 2a, reference numeral 210 is an image obtained by a plurality of cameras, and each image is converted into a top-view image. At this time, the plurality of camera sensors can detect the first to fourth areas (211 to 214) from the top-view image (210). In addition, the plurality of camera sensors can detect a person existing in the first to fourth areas (211 to 214).

When a person is detected from the first to fourth areas (211 to 214), the plurality of camera sensors can transmit detection information to the control unit (110) and/or the judgment unit (160).

Meanwhile, the sensor unit (120) may include a plurality of ultrasonic sensors that detect the movement of an object located in an area around the vehicle.

A plurality of ultrasonic sensors are respectively positioned on or around the front left (FL) tire, the front right (FR) tire, the rear left (RL) tire, and the rear right (RR) tire to detect objects located in the first to fourth areas.

For an example of a layout structure of multiple ultrasonic sensors, refer to Fig. 2b.

Referring to FIG. 2B, the plurality of ultrasonic sensors may include first to fourth sensors (121 to 124). The first sensor (121) may be positioned at or around a front left (FL) tire to detect a person located in a first area (221). The second sensor (122) may be positioned at or around a front right (FR) tire to detect a person located in a second area (222). The third sensor (123) may be positioned at or around a rear left (RL) tire to detect a person located in a third area (223). In addition, the fourth sensor (124) may be positioned at or around a rear right (RR) tire to detect a person located in a fourth area (224).

When a person is detected from the first to fourth areas (211 to 214), the first to fourth sensors (121 to 124) can transmit detection information to the control unit (110) and/or the judgment unit (160).

The output unit (130) may include one or more output means for outputting the operating status and results of the tire pressure monitoring device (100).

As an example, the output unit (130) may include a display that displays a message according to the tire pressure status and/or the tire pressure status. In addition, the output unit (130) may further include a dashboard that lights up a warning light according to the tire pressure status. In addition, the output unit (130) may further include a speaker, buzzer, etc. that outputs a warning sound according to the tire pressure status.

At this time, the display may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, a field emission display (FED), and a 3D display.

The communication unit (140) may include a communication module that supports a communication interface with electrical components and/or control units equipped in the vehicle. As an example, the communication unit (140) may include a communication module that supports signal transmission and reception between sensors equipped in the vehicle and each control unit. Here, the communication module may be a module that supports vehicle network communication such as CAN (Controller Area Network) communication, LIN (Local Interconnect Network) communication, and Flex-Ray communication.

Additionally, the communication unit (140) may include a module for wireless Internet access or a communication module for short range communication.

The storage unit (150) can store data and/or algorithms necessary for the operation of the tire pressure monitoring device (100).

As an example, the storage unit (150) may store tire pressure information. In addition, the storage unit (150) may store condition information for determining whether to allow the tire pressure setting button, and may store information on whether to allow or not to allow the tire pressure setting button. In addition, the storage unit (150) may store commands for guiding corresponding messages according to the allowable or not to allow setting status of the air pressure setting button.

Here, the storage unit (150) may include a storage medium such as RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), PROM (Programmable Read-Only Memory), and EEPROM (Electrically Erasable Programmable Read-Only Memory).

When a low tire pressure condition is detected, the control unit (110) warns of low tire pressure through the output unit (130). For example, the control unit (110) may light a low tire pressure warning light on the instrument panel. In addition, the control unit (110) may display a low tire pressure warning message on the display screen or output a warning sound through an alarm.

After warning of a low tire pressure condition, the judgment unit (160) determines whether a person is detected for a certain period of time or longer within each of the first to fourth areas based on object detection information from multiple sensors while the vehicle is stationary. The judgment unit (160) transmits the object detection judgment results for the first to fourth areas to the control unit (110).

The control unit (110) can set the tire pressure setting button to an allowable or disallowed state based on the judgment result of the judgment unit (160).

For example, the control unit (110) may set the tire pressure setting button to the allowable state if it is confirmed that a person has been detected in all of the first to fourth areas for a certain period of time in a low tire pressure state. On the other hand, the control unit (110) may set the tire pressure setting button to the disallowed state if it is confirmed that a person has not been detected in at least one of the first to fourth areas for a certain period of time in a low tire pressure state.

A tire pressure setting button may be placed on the vehicle. Accordingly, the user (or driver) can operate the tire pressure setting button when resetting the tire pressure after a low tire pressure warning.

When the tire pressure setting button is operated by the user (or driver), the control unit (110) checks whether the tire pressure setting button is allowed or not.

When the tire pressure setting button is in the allowed state, the control unit (110) learns the tire pressure according to the operation of the tire pressure setting button, sets the tire pressure based on the learning result, and stores it. At this time, the control unit (110) can inform the user (or driver) of the completion status of the storage of the tire pressure.

For examples of this, refer to FIGS. 3a and 3b.

Referring to Fig. 3a, if it is confirmed that a person has been detected for a certain period of time or longer from all of the first to fourth areas after the vehicle has stopped in a state of low tire pressure, the control unit (110) sets the tire pressure setting button (21) to an allowed state based on object detection information from the first to fourth areas.

When the tire pressure setting button (21) is operated by a user (or driver) while the control unit (110) is set to the allow state, the control unit (110) learns and stores the current tire pressure, and outputs a notification message indicating that the tire pressure has been stored through the display screen as shown in FIG. 3b.

Meanwhile, if the tire pressure setting button (21) is not allowed, the control unit (110) can output a warning message to guide the user (or driver) to check the four tire pressures and then operate the tire pressure setting button (21) again when the tire pressure setting button (21) is operated.

For examples of this, refer to FIGS. 4a to 7b.

Referring to FIG. 4a, if it is confirmed that a person is detected from the second to fourth areas of the front right (FR), rear left (RL), and rear right (RR) among the first to fourth areas after the vehicle stops in a state of low tire pressure, while no person is detected from the first area of the front left (FL) for a certain period of time, the control unit (110) sets the tire pressure setting button (21) to a non-allowed state based on object non-detection information of the first area.

In this case, if the tire pressure setting button (21) is operated by the user (or driver) while the control unit (110) has set the tire pressure setting button (21) to a non-allowed state, the current tire pressure is not stored. At this time, since the low pressure state of the tire is maintained, the control unit (110) can guide the user to check the four tire pressures as shown in Fig. 4b.

In addition, referring to FIG. 5a, if it is confirmed that a person is detected from the first and fourth areas of the front left (FL) and the rear right (RR) among the first to fourth areas for a certain period of time after the vehicle stops in a state of low tire pressure, while no person is detected from the second and third areas of the front right (FR) and the rear left (RL) for a certain period of time, the control unit (110) sets the tire pressure setting button (21) to a non-allowed state based on object non-detection information of the second and third areas.

In this case, if the tire pressure setting button (21) is operated by the user (or driver) while the control unit (110) has set the tire pressure setting button (21) to a non-allowed state, the current tire pressure is not stored. At this time, since the low pressure state of the tire is maintained, the control unit (110) can guide the user to check the four tire pressures as shown in Fig. 5b.

Referring to FIG. 6a, if it is confirmed that a person is detected for a certain period of time from the fourth area of the rear right (RR) among the first to fourth areas after the vehicle stops in a state of low tire pressure, while no person is detected for a certain period of time from the first to third areas of the front left (FL), front right (FR), and rear left (RL), the control unit (110) sets the tire pressure setting button (21) to a non-allowed state based on object non-detection information of the first to third areas.

In this case, if the tire pressure setting button (21) is operated by the user (or driver) while the control unit (110) has set the tire pressure setting button (21) to a non-allowed state, the current tire pressure is not stored. At this time, since the low pressure state of the tire is maintained, the control unit (110) can guide the user to check the four tire pressures as shown in Fig. 6b.

Referring to Fig. 7a, if it is confirmed that no person has been detected for a certain period of time from any of the first to fourth areas after the vehicle has stopped in a state of low tire pressure, the control unit (110) sets the tire pressure setting button (21) to a non-allowed state based on object non-detection information from the first to fourth areas.

In this case, if the tire pressure setting button (21) is operated by the user (or driver) while the control unit (110) has set the tire pressure setting button (21) to a non-allowed state, the current tire pressure is not stored. At this time, since the low pressure state of the tire is maintained, the control unit (110) can guide the user to check the four tire pressures as shown in Fig. 7b.

As described above, the tire pressure monitoring device (100) according to the present invention can prevent the tire pressure from being stored incorrectly when the tire pressure setting button (21) is incorrectly operated by a user (or driver).

The tire pressure monitoring device (100) according to the present embodiment, which operates as described above, may be implemented in the form of an independent hardware device including a memory and a processor that processes each operation, and may be driven in a form included in another hardware device such as a microprocessor or a general-purpose computer system.

The operation flow of the tire pressure monitoring device according to the present invention configured as described above is described in more detail as follows.

FIGS. 8 to 10 are diagrams illustrating an operational flow for a tire pressure monitoring method according to one embodiment of the present invention.

First, Fig. 8 shows an operation of setting the allowable or disallowable status of the tire air pressure setting button according to the result of determining whether air is injected through the camera.

Referring to Fig. 8, when a low tire pressure condition is detected by the sensor unit (120) (S100), the tire pressure monitoring device (100) warns of a low tire pressure condition (S110).

Thereafter, the tire pressure monitoring device (100) checks whether the vehicle is stopped (S120). If the vehicle is confirmed to be stopped in the 'S120' process, the tire pressure monitoring device (100) wakes up the camera sensor to acquire images of the surroundings of the vehicle (S130, S140). Here, the camera sensors are placed in the front, rear, left, and right directions of the vehicle to acquire images of the surroundings of the vehicle.

The tire pressure monitoring device (100) processes images of each preset tire area from images of the vehicle surroundings acquired from the camera sensor (S150) and determines whether a person has been present in each tire area for a predetermined period of time (S160 to S190). Here, each tire area may be set as a first area corresponding to the surrounding area of the front left tire, a second area corresponding to the surrounding area of the front right tire, a third area corresponding to the surrounding area of the rear left tire, and a fourth area corresponding to the surrounding area of the rear right tire.

If the tire pressure monitoring device (100) determines that a person is present in all of the first to fourth areas for a certain period of time through the 'S160' to 'S190' processes, it determines that air has been injected into each tire and sets the tire pressure setting button (SET button) to the permitted state to store the changed tire pressure (S200).

Meanwhile, if the tire pressure monitoring device (100) determines that no person is present in at least one of the first to fourth areas for a certain period of time through the 'S160' to 'S190' processes, it determines that the tire is not inflated and sets the tire pressure setting button (SET button) to a non-permitted state to prevent low tire pressure from being stored (S210).

In this case, if the tire is not inflated, the tire pressure setting button (SET button) will remain in an unacceptable state.

Figure 9 illustrates an operation for setting the allowable or disallowable status of the tire pressure setting button according to the result of determining whether air is injected through an ultrasonic sensor.

Referring to Fig. 9, when a low tire pressure condition is detected by the sensor unit (120) (S300), the tire pressure monitoring device (100) warns of a low tire pressure condition (S310).

Thereafter, the tire pressure monitoring device (100) checks whether the vehicle is stopped (S320). If the vehicle is confirmed to be stopped in the 'S320' process, the tire pressure monitoring device (100) wakes up the first to fourth sensors to detect the first to fourth areas around the vehicle (S330, S340).

Here, the first to fourth sensors are ultrasonic sensors that detect objects located around the tires. The first to fourth sensors may be installed to correspond to the positions of the respective tires. For example, the first sensor may be installed at a position corresponding to the front left tire and may detect an object located in the first area. In addition, the second sensor may be installed at a position corresponding to the front right tire and may detect an object located in the second area. In addition, the third sensor may be installed at a position corresponding to the rear left tire and may detect an object located in the third area. In addition, the fourth sensor may be installed at a position corresponding to the rear right tire and may detect an object located in the fourth area.

The tire pressure monitoring device (100) analyzes the object detection results for each of the first to fourth areas from the first to fourth sensors (S350) and determines whether a person has been present in the first to fourth areas for a certain period of time or longer (S360 to S390).

If the tire pressure monitoring device (100) determines that a person is present in all of the first to fourth areas for a certain period of time through the 'S360' to 'S390' processes, it determines that air has been injected into each tire and sets the tire pressure setting button (SET button) to the permitted state to store the changed tire pressure (S400).

Meanwhile, if the tire pressure monitoring device (100) determines that no person is present in at least one of the first to fourth areas for a certain period of time through the 'S360' to 'S390' processes, it determines that the tire is not inflated and sets the tire pressure setting button (SET button) to a non-permitted state to prevent low tire pressure from being stored (S410).

In this case, if the tire is not inflated, the tire pressure setting button (SET button) will remain in an unacceptable state.

Figure 10 shows the operation of saving and guiding tire pressure by operating the tire pressure setting button.

After the allowable or unallowable state of the tire pressure setting button (SET button) is set by the processes of FIG. 8 and/or FIG. 9, when a tire pressure setting button (SET button) signal is input due to the user (or driver) operating the tire pressure setting button (SET button) (S510), the tire pressure monitoring device (100) checks the allowable or unallowable setting state of the tire pressure setting button (SET button) (S520).

If the tire pressure monitoring device (100) confirms that the tire pressure setting button (SET button) is in the allowed state in the 'S520' process, it learns and sets the current tire pressure (S530) and informs the result of the tire pressure setting (S540).

If the tire pressure monitoring device (100) determines that the tire pressure setting button (SET button) is not in a permitted state during the 'S520' process, it blocks the storage of tire pressure and guides the user to check the tire pressure status (S550).
